Trying to upgrade any tex related package is a bad idea currently. Seems to be caused by the packages build by src:texlive-bin from version 2013.20130516.30500-1, but manifests itself in other tex packages like tex-common:

Code:

Setting up tex-common (4.03) ...
Running mktexlsr. This may take some time... done.
Running updmap-sys. This may take some time...
updmap-sys failed. Output has been stored in
/tmp/updmap.bBEhK0C5
Please include this file if you report a bug.

Sometimes, not accepting conffile updates in /etc/texmf/updmap.d
causes updmap-sys to fail. Please check for files with extension
.dpkg-dist or .ucf-dist in this directory

In my case, texlive-lang-croatian doesn't have a new version but its files are now in texlive-lang-european. Though it did took a little investigative work to find that out, I'm wondering why apt wasn't instructed to replace texlive-lang-croatian with texlive-lang-european.
